AI Customer ServiceThe lithium battery charging curve illustrates how the battery’s voltage and current change during the charging process. Typically, it consists of several distinct phases: Constant Current (CC) Phase: In this initial phase, the charger applies a constant current to the battery until it reaches a predetermined voltage threshold.
The standard regimen for lithium-ion charging is CCCV charging. During the initial CC phase, the cell is charged with constant current up to its maximum voltage. At that point, the charging automatically transitions to CV phase, where the balance of charging takes place, bringing the cell up to 100% SoC.
Constant current discharge is the discharge of the same discharge current, but the battery voltage continues to drop, so the power continues to drop. Figure 5 is the voltage and current curve of the constant current discharge of lithium-ion batteries.
Full charging can take from under 2, to up to many hours, depending on the charging current applied to the cell. Figure 5: Lithium-ion cell CCCV charging over time. Standard CC Discharging for lithium-ion cells Standard discharging for a lithium-ion cell is more straightforward compared to CCCV charging.
Lithium-based cells – whether solid-state battery or conventional Li-ion battery – are basically similar in structure. There are two electrodes (positive and negative) with a separator between them. When charging, ions migrate from the positive side (cathode) to the negative side (anode) and when discharging, the ions migrate back again.
The voltage is generated by the charging and discharging process of the Li-ions from the anode and cathode. Reactions shown also apply to solid-state batteries, although the choice of material is atypical here, Own illustration. During discharge, the Li-ions migrate from the anode to the cathode. LCO is a cathode with a layered structure.
